Effects of a Group-Mediated Exercise and Dietary Intervention in the Treatment of Prostate Cancer Patients Undergoing Androgen Deprivation Therapy: Results From the IDEA-P Trial.

ABSTRACT: Background:Although androgen-deprivation therapy (ADT) is the foundation of treatment for prostate cancer, the physiological impacts of ADT result in functional decline and enhanced risk of chronic disease and metabolic syndrome. Purpose:The Individualized Diet and Exercise Adherence Pilot Trial (IDEA-P) is a single-blind, randomized, pilot trial comparing the effects of a group-mediated, cognitive-behavioral (GMCB) exercise and dietary intervention (EX+D) with those of a standard-of-care (SC) control during the treatment of prostate cancer patients undergoing ADT. Methods:A total of 32 prostate cancer patients (M age = 66.28, SD = 7.79) undergoing ADT were randomly assigned to the 12-week EX+D intervention (n = 16) or control (n = 16). The primary outcome in IDEA-P was change in mobility performance with secondary outcomes including body composition and muscular strength. Blinded assessment of outcomes were obtained at baseline and at 2- and 3-month follow-ups. Results:Favorable adherence and retention rates were observed, and no serious intervention-related adverse events were documented. Intent-to-treat ANCOVA controlling for baseline value and ADT duration demonstrated that EX+D resulted in significantly greater improvements in mobility performance (p < .02), muscular strength (p < .01), body fat percentage (p < .05), and fat mass (p < .03) at 3-month follow-up, relative to control. Conclusion:Findings from the IDEA-P trial suggest that a GMCB-based EX+D intervention resulted in significant, clinically meaningful improvements in mobility performance, muscular strength, and body composition, relative to controls. Collectively, these results suggest that the EX+D was a safe and well-tolerated intervention for prostate cancer patients on ADT. The utility of implementing this approach in the treatment of prostate cancer patients on ADT should be evaluated in future large-scale efficacy trials. Clinical Trial information:NCT02050906.

Project description:Androgen deprivation therapy (ADT) is the foundation of treatment for men with metastatic prostate cancer and is now frequently incorporated into multimodality strategies for the curative treatment of locally advanced prostate cancer. Nevertheless, the catabolic effects of ADT result in meaningful adverse effects on physiological and quality of life outcomes, which may, in turn, increase the risk of functional decline, frailty, cardiovascular disease, and metabolic syndrome. Recent evidence demonstrates that lifestyle intervention promoting change in exercise and dietary behaviors is a promising approach, and may offset, or even reverse, the adverse effects accompanying ADT. Unfortunately, the limited existing studies of the effects of exercise and dietary interventions targeting patients with prostate cancer on ADT are characterized by high attrition rates and poor postintervention maintenance of treatment effects. Consequently, the Individualized Diet and Exercise Adherence Pilot Trial (IDEA-P) is designed to contrast the effects of a lifestyle intervention designed to promote independent self-management of exercise and dietary behavior with those of standard care disease management approach in the treatment of prostate cancer.A total of 40 patients with prostate cancer undergoing ADT will be randomly assigned to lifestyle intervention or standard care. Outcomes of interest in IDEA-P include changes in self-reported and objectively assessed physical function and physical activity, dietary behavior, body composition, muscular strength, and quality of life. Outcomes will be obtained at baseline, 2-month, and 3-month assessments by trial personnel blinded to participants' randomization assignment.Findings from this study will establish the feasibility and preliminary efficacy of an innovative lifestyle intervention designed to promote progressively independent self-regulated exercise and dietary behavior change in the treatment of patients with prostate cancer undergoing ADT.ClinicalTrials.gov NCT02050906.

Project description:Androgen deprivation therapy (ADT) is the mainstay therapy for men with prostate cancer. However, there are musculoskeletal side effects from ADT that increase the risk for osteoporosis and fracture, and can compromise the quality of life of these individuals. The objectives of this study are to determine the efficacy of a home-based walking exercise program in promoting bone health, physical function and quality of life in men with prostate cancer receiving ADT.A 12-month prospective, single-blinded, randomized controlled trial will be conducted to compare the Exercise Group with the Control Group. Sixty men with prostate cancer who will be starting ADT will be recruited and randomly assigned to one of the two groups: the Exercise Group will receive instructions in setting up an individualized 12-month home-based walking exercise program, while the Control Group will receive standard medical advice from the attending physician. A number of outcome measures will be used to assess bone health, physical function, and health-related quality of life. At baseline and 12 months, bone health will be assessed using dual-energy X-ray absorptiometry. At baseline and every 3 months up to 12 months, physical function will be evaluated using the Functional Assessment of Chronic Illness Therapy - Fatigue Scale, Activities-specific Balance Confidence Scale, Short Physical Performance Battery, and Six-Minute Walk Test; and health-related quality of life will be assessed using the Functional Assessment of Cancer Therapy Prostate Module and the Medical Outcomes Study 12-item Short Form Health Survey Version 2. A mixed multiple analysis of variance will be used to analyze the data.Musculoskeletal health management remains a challenge in men with prostate cancer receiving ADT. This study addresses this issue by designing a simple and accessible home-based walking exercise program that will potentially have significant impact on reducing the risk of fracture, promoting physical function, and ultimately improving the health-related quality of life in men with prostate cancer receiving ADT.ClinicalTrials.gov: NCT00834392.

Project description:ObjectivesAndrogen deprivation therapy (ADT) has seen increasing use as a prostate cancer treatment in recent years and has proven medically effective in numerous contexts. The treatment, however, is associated with a host of side effects including depression. Managing the psychological wellbeing of prostate cancer patients is important for maximizing their survival outcomes. Thus, this study aimed to evaluate depressive symptomatology in patients with androgen deprivation therapy (ADT) compared with that in patients who underwent prostatectomy and to explore the factors that affect depressive symptoms, which might occur during ADT.MethodsOne hundred and seven patients undergoing ADT (ADT group) and prostatectomy (Operation group) were enrolled. Adjustments were made for differences in characteristics between groups using a propensity score model with stabilized weights before treatment. Depressive symptoms between groups were compared using the Beck Depression Inventory (BDI) before treatment and six months after treatment initiation. To identify factors affecting depressive symptoms during ADT, multivariate regression analysis was performed on the mean change in BDI score, age, body mass index, testosterone level, prostate-specific antigen level, the international index of erectile function (IIEF), and the Gleason score.ResultsThe BDI score significantly increased in the ADT group compared to the operation group six months after treatment initiation (p < 0.001). Multivariate regression analysis revealed that before ADT, the BDI score was higher by 0.446 according to the IIEF. During ADT, the BDI score increased by 1.579 according to changes in BMI (p = 0.021) and decreased by 0.01 according to changes in testosterone levels (p = 0.034).ConclusionDepressive symptoms can be exacerbated in prostate cancer patients undergoing ADT. Efforts are needed to diagnose and treat depression appropriately, especially if depressive symptoms change in ADT patients with a high IIEF score before ADT, or reduced testosterone levels or increased BMI during ADT.

Project description:BACKGROUND:National guidelines (NICE-CG175) recommended 12 weeks of supervised exercise training for men treated with androgen deprivation therapy (ADT) for prostate cancer to counter debilitating adverse effects of castration. As with other chronic conditions where exercise is indicated, it is uncertain if these services are being delivered in the health services. The aim of this multi-centre investigation was to examine what exercise referral is currently available for men on ADT as provided by the NHS and if a supervised, individually-tailored exercise training package (as per the national NICE guidelines CG175) is embedded within prostate cancer care. METHODS:A multi-centre investigation of current National Health Service (NHS) care involving a web-based survey of NHS prostate cancer care, five focus groups involving 26 men on ADT and 37 semi-structured interviews with healthcare professionals (HCPs) involved in the management of prostate cancer. Descriptive statistics and thematic analysis evaluated quantitative and qualitative data, respectively. Qualitative methods followed COREQ standards. RESULTS:HCPs and men on ADT asserted that medical castration has a serious and debilitating impact on many features of men's quality of life. There is support for exercise training programmes as part of cancer care and patients would support their initiation soon after diagnosis. Involving the Multidisciplinary Team (MDT) is proposed as key to this. Critically, traditional values in oncology would need to be overcome for widespread acceptance. Specialist further training for HCPs around behaviour change support could encourage this. Given that these schemes are seen as a fundamental part of cancer care, it is felt the NHS should commission and support provision. 79 representatives of 154 NHS trusts (51%) provided survey data on current delivery: only 17% could provide supervised exercise as per CG175. CONCLUSIONS:Evidence-based national exercise guidelines are not being delivered to men on ADT as intended. Traditional values in oncology and the need for NHS financial support are seen as major barriers to provision of current best practice guidelines. Despite this both HCPs and men on ADT are in favour of such programmes being a fundamental part of their cancer care.
